Bio-MIL-PRF-32073 Hydraulic Fluid
(ISO 15, 22, 32, 46, 68)
"Biobased Lubricants that Perform Like Synthetics"
Bio-MIL-PRF-32073 Hydraulic Fluids are ultimately biodegradable1,biosynthetic (biobased) formulas that were
designed to replace mineral oil based hydraulic fluids for environmentally sensitive areas. They have been
specifically formulated to provide additional seal swell (10% to 30%) as required by MIL-PRF-32073 and ISO 15
or ISO 22 can replace obsolete specification MIL-PRF-5606 for ground support equipment. Bio-MIL-PRF32073 Hydraulic Fluids are formulated to perform in hydraulic systems that require anti-wear, anti-foam, antirust, anti-oxidation, and demulsibility properties. They are highly inhibited against moisture and rusting in both
fresh and sea water and pass both A and B Sequences of the ASTM D-665 Turbine Oil Rust Test. Incorporating
the super high viscosity index of the Stabilized* High Oleic Base Stocks (HOBS) into the formula, gives multigrade synthetic base oil performance by boosting the viscosity index to synthetic levels. This super high
viscosity index of the HOBS naturally improves the thermal shear stability of the formula and increases load
capacity. The HOBS’s extremely low volatility increases the flash and fire safety features in the formula. An
environmentally friendly, zinc-free additive system has also been developed that meets or exceeds high pressure
pump requirements.
Bio-MIL-PRF-32073 Hydraulic Fluids have been used successfully in a wide variety of stationary and mobile
hydraulic equipment. These patented super high VI fluids are designed for use in hydraulic vane, piston, and
gear-type pumps. They also meet the requirements for ashless GL-1, GL-2, GL-3 and AGMA Non-EP gear oils
in reduction units and gear sets where they meet the viscosity ranges. They have shown to have exceptional antiwear performance in ASTM D-4172 Four Ball Wear Tests. Very little wear was encountered in the field
studies, and in accelerated pump tests using biobased formulations in Denison T-5D, Vickers 20VQ,
35VQ-25 (M-2950-S), and V-104C (ASTM D-2882), Vickers I-286-S pump stand tests. Their anti-wear
performance exceeds the requirements for US Steel 126, 136 and 127, load stage 10 in the FZG (DIN 51354).
Bio-MIL-PRF-32073 Hydraulic Fluids meet the Environmental Protection Agency (EPA) 2013 Vessel General
Permit (VGP) guidelines for Environmentally Acceptable Lubricants (EALs), and should be used in hydraulic
systems where LOW TOXICITY, BIODEGRADABILITY and NON-BIOACUMMULATION properties
are required. They exceed the acute toxicity (LC-50 / EC-50 >1000 ppm) criteria adopted by the US Fish and
Wildlife Service and the US EPA.
Bio-MIL-PRF-32073 Hydraulic Fluids are ENVIRONMENTALLY RESPONSIBLE lubricants that are formulated from
renewable agricultural biobased resources. We believe Earth's environmental future rests in the use of renewable materials.

STABILIZED by Renewable Lubricants™* is RLI’s trademark on their proprietary and patented anti-oxidant, anti-wear, and cold flow
technology. High Oleic Base Stock (HOBS) are agricultural vegetable oils. This Stabilized technology allows the HOBS to perform as
a high performance formula in high and low temperature applications, reducing oil thickening and deposits.

Bio-MIL-PRF-32073 Hydraulic Fluid
The test data below shows that the Bio-MIL-PRF-32073 Hydraulic Fluids provide high performance in a wide
variety of stationary and transportation equipment that operate in broad ranges of environmental conditions.
In equipment operating outside, wear from poor cold temperature pumpability, surge loads, moisture, and
dusty environments are more prominent. Bio-MIL-PRF-32073 Hydraulic Fluids are formulated to improve
performance in equipment that requires excellent anti-wear, rapid water separation and cold temperature
pumpability as low as -400C. In addition, the products may be used in machine tool hydraulic systems where
higher seal swell fluids are required because of previously used MIL-Spec hydraulic Fluids.
